Why Choose the Mersen NH2UD69V160PV Protistor® High-Speed Fuse?
The Mersen NH2UD69V160PV is a Protistor® NH Size 2 high-speed semiconductor fuse designed to protect sensitive power electronic equipment against damaging short-circuit currents. Rated at 160 A and 690 V AC, it provides rapid fault interruption for demanding industrial applications involving semiconductor devices such as IGBTs, thyristors, diodes and rectifier modules.
Featuring an aR utilisation category, the NH2UD69V160PV is intended specifically for partial-range semiconductor protection. Its fast-acting, current-limiting performance helps reduce the let-through energy reaching valuable electronic components, minimising thermal and mechanical stress during severe fault conditions.
The fuse has an industrial NH Size 2 square-body format with blade contacts for installation in compatible NH fuse bases, holders and switch-disconnectors. Its robust ceramic construction and internal fuse-element technology make it suitable for drives, converters, UPS equipment, renewable-energy systems and other power-electronic assemblies.

Designed for High-Speed Semiconductor Protection
Semiconductor devices can sustain permanent damage in a fraction of the time required for a conventional industrial fuse to operate. Protistor® high-speed fuses use specialised fuse elements to interrupt severe fault currents quickly, limiting the energy passed into the protected equipment.
The aR classification means the NH2UD69V160PV provides dedicated short-circuit protection rather than full-range overload protection. Where overload protection is required, the fuse must be correctly coordinated with an additional protective device in accordance with the equipment design and applicable electrical standards.
Typical Applications
- Variable frequency drives and industrial motor drives.
- Power converters and inverter systems.
- Industrial rectifiers.
- Uninterruptible power supply equipment.
- Renewable-energy power conversion systems.
- Soft starters and servo-drive equipment.
- Protection of IGBTs, thyristors and diode modules.
- Industrial automation and power-control panels.
